            HEICO REPORTS RECORD QUARTERLY SALES AND OPERATING INCOME
                                IN THIRD QUARTER

          49% Increase in Operating Income on 24% Increase in Net Sales

HOLLYWOOD, FL and MIAMI, FL -- HEICO CORPORATION (NYSE: HEI.A) (NYSE: HEI) today
reported net sales for the third quarter of fiscal 2005 increased 24% to
$69,169,000 from $55,820,000 in the third quarter of fiscal 2004 and increased
25% to $193,123,000 in the first nine months of fiscal 2005 from $154,764,000 in
the first nine months of fiscal 2004.

Operating income was up 49% to a record $11,749,000 for the third quarter of
fiscal 2005 from $7,870,000 for the third quarter of fiscal 2004 and up 41% to a
record $31,843,000 for the first nine months of fiscal 2005 from $22,615,000 for
the first nine months of fiscal 2004.

Net income for the third quarter of fiscal 2005 was $6,046,000, or 23 cents per
diluted share, versus $8,115,000, or 32 cents per diluted share, in the third
quarter of fiscal 2004. Fiscal 2004 third quarter net income included one-time
income of $4.0 million (16 cents per diluted share) in proceeds from a
key-person life insurance policy. Net income for the first nine months of fiscal
2005 increased 5% to $16,187,000, or 62 cents per diluted share, from
$15,464,000, or 60 cents per diluted share, in the first nine months of fiscal
2004, which included the one-time $4.0 million (16 cents per diluted share) in
life insurance proceeds.

(NOTE: HEICO has two classes of common stock traded on the NYSE. Both classes,
the Class A Common Stock (HEI.A) and the Common Stock (HEI), are virtually
identical in all economic respects. The only difference between the share
classes is the voting rights. The Class A Common Stock (HEI.A) receives 1/10
vote per share and the Common Stock (HEI) receives one vote per share.)

Laurans A. Mendelson, HEICO's Chairman, President & Chief Executive Officer,
remarked, "We are extremely pleased to report record quarterly net sales and
operating income for the second consecutive quarter. Both our Flight Support
Group and our Electronic Technologies Group reported increased net sales of 25%
and 21%, respectively, over the third quarter of fiscal 2004.

                                    - more -


All the sales increase within the Flight Support Group was organic growth,
reflecting the continued recovery in aftermarket demand within the commercial
airline industry, as well as our continued success in the development of new
products and services for our customers. The sales increase within our
Electronic Technologies Group principally reflects strong results from two
strategic acquisitions made earlier in fiscal 2005.

Operating income of our Flight Support Group increased 74% to $10.5 million for
the third quarter of fiscal 2005 up from $6.0 million for the third quarter of
fiscal 2004 and increased 55% to $26.9 million for the first nine months of
fiscal 2005 up from $17.3 million for the first nine months of fiscal 2004. The
increase in operating income of the Flight Support Group for the third quarter
of fiscal 2005 and the first nine months of fiscal 2005 reflects both the
increase in net sales and higher operating margins resulting principally from
improved operating efficiencies. Operating margins of the Flight Support Group
improved to 20.8% in the third quarter of fiscal 2005 from 15.0% in the third
quarter of fiscal 2004 and improved to 19.4% in the first nine months of fiscal
2005 from 15.5% for the first nine months of fiscal 2004.

Operating income of our Electronic Technologies Group increased 11% to
$3.8 million for the third quarter of fiscal 2005 up from $3.4 million for the
third quarter of fiscal 2004 and increased 9% to $10.5 million for the first
nine months of fiscal 2005 up from $9.6 million for the first nine months of
fiscal 2004. Operating margins of the Electronic Technologies Group were 20.1%
in the third quarter of fiscal 2005 and 19.2% in the first nine months of fiscal
2005, down slightly from 21.8% in the third quarter of fiscal 2004 and 22.5% for
the first nine months of fiscal 2004, due principally to a less favorable
product sales mix. Based on the current backlog within our Electronic
Technologies Group, we expect operating margins for the full fiscal 2005 year to
approximate 20%.

Our consolidated operating margins improved to 17.0% in the third quarter of
fiscal 2005 from 14.1% in the third quarter of fiscal 2004 and to 16.5% for the
first nine months of fiscal 2005 from 14.6% for the first nine months of fiscal
2004.

Cash flow from operating activities for the first nine months of fiscal 2005
totaled $21.0 million versus $32.6 million in the first nine months of fiscal
2004 principally due to a higher investment in inventories required to meet
increased sales demand and longer lead times for certain raw materials, as well
as increased accounts receivable due to the higher sales levels. In light of
these required investments in working capital, we are revising our fiscal 2005
targeted cash flow from operating activities to a range of $30 to $35 million.
Our net capital expenditure budget for fiscal 2005 remains in the range of $6 to
$8 million, net of $3.5 million in proceeds we received from the sale of an
excess facility.

Based on current market conditions, we continue to target fiscal 2005
consolidated sales of approximately $255 to $260 million and diluted net income
per share in the range of $.84 to $.86. The net sales and earnings targets
exclude the impact of additional acquisitions, if any.

As we look to the remainder of fiscal 2005, fiscal 2006 and beyond, we believe
the increasing product demand from the commercial airline industry, our
commitment to develop new products

                                    - more -


and services, our strong financial position and select acquisition opportunities
provide the foundation for long-term growth in sales and earnings."

Certain statements in this press release constitute forward-looking statements,
which are subject to risks, uncertainties and contingencies. HEICO's actual
results may differ materially from those expressed in or implied by those
forward-looking statements as a result of factors including, but not limited to:
lower demand for commercial air travel or airline fleet changes, which could
cause lower demand for our goods and services; product specification costs and
requirements, which could cause an increase to our costs to complete contracts;
governmental and regulatory demands, export policies and restrictions,
reductions in defense or space spending by U.S. and/or foreign customers, or
competition from existing and new competitors, which could reduce our sales;
HEICO's ability to introduce new products and product pricing levels, which
could reduce our sales or sales growth; HEICO's ability to make acquisitions and
achieve operating synergies from acquired businesses, customer credit risk,
interest rates and economic conditions within and outside of the aviation,
defense, space and electronics industries, which could negatively impact our
costs and revenues; and HEICO's ability to maintain effective internal controls,
which could adversely affect our business and the market price of our common
stock. Parties receiving this material are encouraged to review all of HEICO's
filings with the Securities and Exchange Commission, including, but not limited

HEICO CORPORATION
FOOTNOTES TO CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (Unaudited)

- ----------

(1)  Operating income was reduced in fiscal 2004 by an aggregate of $600,000 in
     restructuring expenses recorded by certain subsidiaries of the Flight
     Support Group that provide repair and overhaul services including $350,000
     recorded in cost of sales and $250,000 recorded in selling, general and
     administrative expenses. The restructuring expenses decreased net income by
     $301,000, or $.01 per basic and diluted share.

(2)  Represents proceeds from a $5.0 million key-person life insurance policy
     maintained by a subsidiary of the Flight Support Group. The minority
     interest's share of this income totaled $1.0 million, which is reported as
     a component of minority interests' share of income. Accordingly, the life
     insurance proceeds increased fiscal 2004 net income by $4.0 million, or
     $.17 per basic and $.16 per diluted share.

(3)  Fiscal 2005 results reflect increased costs to comply with the
     Sarbanes-Oxley Act of 2002 and higher accrued performance awards.
